Methyl bromide and 1,3-dichloropropene failed to eradicate either nematodes or fanleaf virus from the soil but both reduced numbers of nematodes and incidence of disease to levels that were judged acceptable. Carbon disulfide neither reduced nematodes nor disease incidence to levels that were judged acceptable. Vine yields at one site treated with 1,3-dichloropropene remained productive for a period of 10 years at a rate high enough to justify treatment even though nematodes and fanleaf virus were slowly spreadng within the replanted vineyard. Wet soils and soils with high clay content prevented successful control of nematode and virus by any material.
